To all whom t may concern: A

Be it known that I, FRANK D. POWELL, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Indexing Systems, of whichthe following is a specication.

This invention relates to improvements in indexing systems and refers more particularly to a system employing a frame or holder in which are inserted flexible line strips upon which printed matter is put and the line strips inserted in the frame between overlapping lips or channels.

Among the salient objects of the invention is to provide a construction in which a frame may consist of one or more columns of the line strips which are preferably constructed of a flexible substance, andwhose surface is of a character which will take printed matter or typewriting and at the same time offer a smooth durable wearing surface.

Fig. l in the drawing shows a face view of the frame pivoted at one of its lateral edges to swing in a vertical position.

Fig. 2 is an enlarged sectional detail view of one of the columns in which the line strips are positioned.

Fig 3 is a view of the strips made up in the form of a sheet and scored or partially cut so that they may be easily separated or detached from the sheet. l

Fig. 4 is a sectional view taken along the line lf-4 in Fig. 3.

Fig. 5 is a perspective of one of the detached line strips.

Referring to the drawings, the frame consists of a central web or ller l which has a plurality of flanges or lips 2 riveted, spot welded or otherwise attached to the web of the frame. The pivoted edge of the frame has afHxed thereto the pintles 3 which are inserted in holes or eyes in a suitable standard, not shown. The web is corrugated as shown at 4 and 5 near each of the lateral lips or flanges, one of the corrugations tsextending above the surface of the web, and the contour of the second corrugation 5 being raised below the surface of the web. The

function of these' corrugations or ridges is to facilitate the insertion of the line strips 6, and also serve to hold the line strips more lixedly in place after their ends have been inserted beneath the lateral flanges 2.

In addition to the holding proclivities and the ease of insertion, the line strips may be more easily withdrawn and replaced due to the fact that thelingers may be put above and below the strip, and the adjacent strips slightly depressed so that the strip to be removed can be grasped and easily withdrawn from the holding flanges.

The line strips are preferably made up in the form of a sheet so that printed or type written matter may be written on the space of the strips while they are in sheet form.

The strips shown comprise a body portion 7 of wood veneer, to the faces of the wood being glued sheets of paper 8. The sheet is then passed through a cutter which partially cuts the strips through the upper paper sheet and wood veneer, leaving the lower sheet intact as shown in Fig. ll. Thus the strips remain in a sheet unit and may be rotated upon the platen of a typewriter where data can be printed upon the individual strips. The strips are then separated from the sheet by simply tearing the individual lines from the sheet and doubling them centrally to foreshorten their length in order to insert the endsbeneath the flanges 2 of the frame.

It will be readily appreciated that the frames may be made reversible and any number of columns be used upon a single web. The constituents making up the strips may also be varied without departing from the subject of the invention, which lies primarily in the use of a corrugated web which serves to hold the strips more rigidly in place, and facilitate their insertion and replacement.

I claim as my invention:

l. In an indexing system, the combination with a reversible frame, consisting of a web having a plurality of flanges positioned to form columns and adapted to engage the ends of flexible members, a plurality of longitudinally extending staggered raised portions adjacent and parallel to the flanges formed in both sides of the web, and funetioning to assist in holding the strips and facilitating .their removal.
